I'm
using an old TI-85 calculator that I've had since high school. I couldn't
find a wayto get it to calculate median and quartiles, so I wrote
a program to do it.I've tested it and it seems to work right, but I'd recommend
that anybody using it be sure to test it first, ifonly to make sure it's typed in right.

Notes:----------------------------

VARIABLES

[xStat] -- defined in STAT or LIST editor

qL -- temporarily stores sorted list

q5s -- five-number summary

qsize -- length of qL

qql -- current quartile locator

MISC

After running the program, if you need to see the result
again, just type q5son a line by itself and hit enter. It'll store the values
until you changeit, delete it, or run the program again.The program doesn't take yStat into account, so it doesn't
work withfrequency tables. It also doesn't draw boxplots. It takes
a single list ofnumbers (in xStat) and returns {min, Q1, median, Q3,
max}.
